When a Hero rescues a Lost Soul, the player takes the card and puts it in their 'Land of Redemption' to keep score. When a player draws one from their deck, they immediately put it into play in a region called the 'Land of Bondage' and draw another card from their deck to replace it in their hand.

Lost Soul: These represent people who have fallen from the path of goodness and need to be saved.

Most types of cards are indicated by an icon in a box in the card's upper-left corner. Evil characters can prevent the opponent from winning, but they themselves do not have a chance to win the game.

One unique aspect that sets Redemption apart from other CCGs is that while every deck contains both good and evil characters, the game is only won by using good characters. Restrictions or penalties are instead placed on the special abilities of the cards themselves in order to balance game play. Unlike popular trading card games like Pokémon and Magic: The Gathering, Redemption has no built-in resource system that is, players are not required to meet any requirements or pay any costs in order to put cards into play. After the battle, the winning character remains in play and can be used again on the next turn, and the losing character as well as all Enhancements played during the battle are discarded. When both players have finished playing Enhancements, the player whose character's Strength is equal to or higher than their opponent's Toughness wins the battle if the Hero defeats the Evil Character (either by having higher Strength or by removing the Evil Character from the battle via a special ability), the Hero rescues the Lost Soul. In a battle, players take turns playing Enhancement cards to make their characters stronger. The opponent then plays an Evil Character to block the rescue attempt and start a battle. To rescue a Lost Soul, a player must initiate a rescue attempt by playing a Hero. The object of the game is to rescue the required number of Lost Souls (usually five) before the opponent does.
